Remote access
Remote access is defined as the ability of a user to log onto a network from a distant location. This is accomplished with a remote computer connected to the distant network. Whereas remote control refers to taking control of another computer, remote access means that the remote computer becomes a work station on the network. Communication between the network facility equipment and the remote computer is accomplished through a data link. The only difference between a remote user and workstations connected directly to the network is slower data transfer speeds. Remote Access is also useful when you want to connect local office computers with corporate networks. This allows the business to share resources as if all computers are connected to the same LAN. Two common methods of providing this type of remote access are dial-up and Virtual Private Network (VPN).
Dial-up remote access is when a client uses the telecommunications infrastructure to create a physical connection with a remote access server, which is attached to a Local Area Network (LAN). The physical or logical connection between the remote access server and the remote access client is made possible through dial-up equipment. Dial-up remote access is considered a private communication portal. The nature of the dial-up equipment and WAN infrastructure varies, depending on the type of connection. There are several telecommunications technologies can make up the WAN infrastructure used in dial-up remote access. These technologies include Plain Old Telephone Service (POTS), T-carriers, Integrated Services Digital Network (ISDN), Asynchronous Transfer Mode (ATM), and Digital Subscriber Line (DSL). The remote access software dials in...

Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Two routers demark the border between internet and intranet. Internal to these routers are two more routers, creating the appearance of a demilitarized zone (DMZ). However, there are access points, the wireless antenna system and the remote access server (RAS), that provide deeper intranet access that do not rely on the DMZ, rendering the latter rather decorative than substantial. Lastly, there is the virtual private network (VPN) that makes use of the edge routers and provides greater intranet access. Over all, there are four access points: VPN, two edge routers, the RAS, and the wireless system. The RAS, VPN, and wireless provide internal access.
In the following report I will discuss the role of network management and how the network manager contributes to the network security of an organisation. Network security will be discussed in full to inform on how big of an impact network attacks can have on an organisation. Once the impact of network security has been covered I will go through all possible threats that can harm an organisation and the steps network managers should go through to secure a network to the best of their ability. The importance of network tools will be introduced last along with benefits they can provide.
Remote control software can solve many of the problems that an administrator or user can encounter on a local area network. Using a remote-control program, one can access a PC remotely to exchange files between systems, run applications, take control of a client PC or server in order to troubleshoot a problem, and much more.

Site to site VPN's extend the wide area network in the sense that they provide large scale encryption between multiple sites such as remote offices and central offices, and also over the internet. There are two main types of site to site virtual private networks, internet and extranet (HowStuffWorks.com). Intranet based VPN's are used for connecting one or more remote locations to the existing LAN, while an extranet based systems connect one or more different companies to the existing LAN to create a shared environment or partnership.
Remote access is a tricky concept to comprehend mostly due to the complexity of all of the different steps and process that all have to work together to ensure secure connections. The number one priority for any company is to make sure networks are secured. With a good portion of our workforce working remotely it can make that task even more difficult. To make sure that our employees devices whether company issued or personal are healthy enough to make those connections we use the NAP functionality of Windows Server 2012 to ensure compliance.
Huge companies also take advantage of VPN connection. Corporate VPN connections allow companies to communicate with privacy. People can send media files, data, and information through an intranet with security. This serves as a secure line that offers protection to confidential data and information.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
Para empleados que ya están familiarizados con las técnicas para navegar por la Red, el aprender como navegar por la intranet de la compañía requiere poco entrenamiento. La página de Web de la intranet posee el mismo interfaz gráfico basado en "apuntar y pulsar". Mientras que el estar conectada a Internet es algo útil en una intranet, no es algo esencial. Incluso aunque conecten de forma externa, las compañías restringen el acceso desde Internet construyendo un firewall o muro de fuego. Existiendo tanta información de la compañía accesible a través de servidores internos, la seguridad es siempre una prioridad.
In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
Remote Access | As more of the knowledge based workforce become more mobile, the ability to be able to access cooperate data while not in the office is essential to employee productivity. This not only increases mobile employees’ productivity, but also has a significant impact on other employees and their productivity since information can be updated in the central corporate database providing near real-time information.
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
